http://www.terragon.com/tkobrien/algebra/index2.html This online teacher site is all about graphing linear equations. That is what we will be covering next in our Algebra Chapter. Every year my students start to struggle at this point. This is a helpful site that tells the basics of graphing. It does have a plotter tool that doesn’t seem to be working too well for me. Other than that, it helps students learn and there are even assessment tools here.
